Crystalline deformation

In materials science, slip is the large displacement of one part of a crystal relative to another part along crystallographic planes and directions. Slip occurs by the passage of dislocations on close/packed planes, which are planes containing the greatest number of atoms per area and in close-packed directions (most atoms per length). Close-packed planes are known as slip or glide planes. A slip system describes the set of symmetrically identical slip planes and associated fa… WebSep 27, 2024 · Here, we report on the experimental observation of a large tensile elastic deformation with an elastic strain of >4.3% in a Cu-based single crystalline alloy at its …

WebThis paper reviewed the research progress of studies on the crystal rotation of single crystals that were deformed by tension and shear and the influences of crystal rotation and dislocation evolution on strain hardening behavior in crystals that were deformed with different initial orientations. The crystal rotation is entirely different depending on … WebFurther deformation causes grain sizes to decrease to <0.5 μm, with observable kinking in the crystal lattices (defined here as initially undistorted grains folded about a distinct axis in an angular manner). Kinking of the crystal lattices is often associated with the development of porosity in the hinges of these kinks (Figure 3c).
